SPRINKLER

INSTALLATION GUIDE

1. DESCRIPTIONViking residential automatic sprinklers are equipped with a “fast response” heat-sensitive operating element designed to respond

individually and quickly to a specific high temperature. Viking residential sprinklers are designed to combine speed of operation with

water distribution characteristics to help in the control of residential fires and to improve life safety by prolonging the time available

for occupants to escape or be evacuated.

2. LISTINGS AND APPROVALSRefer to the Approval Charts on the appropriate sprinkler technical data page(s) and/or approval agency listings.

A. Viking residential sprinklers are intended for use in the following occupancies: one- and two-family dwellings and mobile homes

with the fire protection sprinkler system installed in accordance with NFPA 13D; residential occupancies up to four stories in height

with the fire protection system installed in accordance with NFPA 13R; or residential portions of any occupancy with the fire protec-

tion system installed in accordance with NFPA 13. Information contained in this guide is based on NFPA 13, “Standard for the

Installation of Sprinkler Systems”.

B. The design criteria for residential sprinklers contained in the NFPA installation standards must be followed except as modifiedby the individual UL 1626 listing information provided in the technical data pages and this Residential Sprinkler Installation Guide

For listed areas of coverage, technical data, and specific design and installation instructions, refer to the appropriate Viking techni-

cal data page for the sprinkler model used.

C. Viking residential sprinklers listed by Underwriters Laboratories, Inc. (UL) have passed fire tests designed to represent fire

conditions for the sprinkler’s listed area of coverage. The standards for residential sprinkler performance and spray patterns are

printed in Underwriters Laboratories Publication UL 1626, “Standard for Residential Sprinklers for Fire Protection Service”. Al

listed Viking residential sprinklers meet or exceed UL 1626 performance requirements and spray pattern criteria for their listed

areas of coverage.

D. NFPA standards allow use of residential sprinklers with rates, design areas, areas of coverage, and minimum design pressures

other than those specified in the standards when they have been listed for such specific residential installation conditions.

3. TECHNICAL DATASpecifcations:

Refer to the appropriate sprinkler technical data sheet.

Material Standards:

Refer to the appropriate sprinkler technical data sheet.

4. INSTALLATIONA. Care and Handling (also refer to Bulletin - Care and Handling of Sprinklers, Form No. F_091699.)

Sprinklers must be handled with care and protected from mechanical damage during storage, transport, handling, and after installation

Store sprinklers in a cool, dry place in their original container.

Use care when locating sprinklers near fixtures that can generate heat.

Never install sprinklers that have been dropped, damaged in any way, or exposed to temperatures exceeding the maximum ambi

ent temperature allowed (refer to Table 1.)

Never install any glass-bulb sprinkler if the bulb is cracked or if there is a loss of liquid from the bulb. A small air bubble should be

present in the glass bulb. Any sprinkler with a loss of liquid from the glass bulb or damage to the fusible element should be

destroyed immediately. (Note: Installing glass bulb sprinklers in direct sunlight (ultraviolet light) may affect the color of the dyeused to color code the bulb. This color change does not affect the integrity of the bulb.)

Viking residential sprinklers are intended for use on wet pipe residential systems only. Adequate heat must be provided for wet-

pipe systems. DO NOT use Viking residential sprinklers on dry systems unless specifically allowed by recognized installation

standards or the Authority Having Jurisdiction.

Residential concealed sprinklers must be installed in neutral or negative pressure plenums only!

Corrosion-resistant sprinklers must be installed when subject to corrosive atmospheres. NOTE: Viking residential sprinklers are

not intended for use in corrosive environments.

B. Installation Instructions

Viking sprinklers are manufactured and tested to meet the rigid requirements of approving agencies. They are designed to be in-

stalled in accordance with recognized installation standards NFPA 13, NFPA 13R, and NFPA 13D, and any associated TIAs.

2 The temperature rating is stamped on the sprinkler.

3 Based on NFPA-13. Other limits may apply, depending on fire loading, sprinkler location, and other requirements of the Authority Having Jurisdiction.

Refer to specific installation standards.

Deviation from the standards or any alteration to the sprinklers or cover plate assemblies after they leave the factory including,

but not limited to: painting, plating, coating, or modification, may render the sprinklers inoperative and will automatically nullify the

approval and any guarantee made by Viking.

The use of residential sprinklers may be limited due to occupancy and hazard. Residential fire protection systems must be designed

and installed only by those who are completely familiar with the appropriate standards and codes, and thoroughly experienced in

fire protection design, hydraulic calculations, and sprinkler system installation.

Before installation, be sure to have the appropriate sprinkler model and style, with the correct K-Factor, temperature rating, and

response characteristics. Viking residential sprinklers must be installed after the piping is in place to prevent mechanical damage.

Keep sprinklers with protective caps or bulb shields contained within the caps or shields during installation and testing, and any time

the sprinkler is shipped or handled.

1a. For frame-style sprinklers, install escutcheon (if used), which is designed to thread onto the external threads of the sprinkler*.

*Refer to the appropriate sprinkler technical data page to determine approved escutcheons for use with specific sprinkler models.

1b. For flush and concealed style sprinklers: Cut the sprinkler nipple so that the ½” or 3/4” (15 mm or 20 mm) NPT** outlet of the

reducing coupling is at the desired location and centered in the opening** in the ceiling or wall. **Size depends on the sprinkler model used. Refer to appropriate sprinkler data page.

SPRINKLER

INSTALLATION GUIDE

DESIGN CRITERIA

For Systems Designed to NFPA 13D or NFPA 13R: Apply the listed areas of coverage and minimum water supply requirements shown in

the approval charts on the residential sprinkler data pages. The sprinkler flow rate is the minimum required discharge from each of the total

number of design sprinklers as specified in NFPA 13D or NFPA 13R.

For Systems Designed to the latest edition of NFPA 13: The number of design sprinklers is to be the four most hydraulically demanding

sprinklers. The minimum required discharge from each of the four sprinklers is to be the greater of the following:

The flow rates given in the approval charts on the data pages for NFPA 13D and NFPA13R for each area of coverage listed, or

Calculated based on a minimum discharge of 0.1 gpm/sq. ft. over the “design area” in accordance with sections 8.5.2.1 or 8.6.2.1.2 of NFPA 13.

The greatest dimension of the coverage area cannot be any greater than the maximum areas of coverage shown on the data pages.

•

•

Flow Rates

All residential sprinklers manufactured on or after July 12, 2002 are listed with a single minimum flow rate. Where rooms have more than one sprinkler,

multiple-sprinkler calculations are still required, but the first sprinkler and any additional sprinkler or sprinklers must be calculated flowing at identical mini-mum flow rates, based on the area of sprinkler coverage, using the minimum flow and pressure listed for the sprinkler model used.

Consult the appropriate standards and the Authorities Having Jurisdiction to determine the number of sprinklers to hydraulically calculate to verify ad-

equate water supply for multiple-sprinkler operation.

Operating Pressure: The minimum operating pressure of any sprinkler shall be the minimum operating pressure specified by the listing, or 7 psi (0.5

bar), whichever is greater. The maximum allowable operating pressure is 175 psi (12 bar).

Areas of Coverage

If the actual area of coverage is less than the listed area of coverage, use the minimum water supply for the next larger area of coverage listed. DO NOT

interpolate. Residential sprinkler systems must be hydraulically calculated according to NFPA standards to verify that the water supply is adequate for

proper operation of the sprinklers. Hydraulic calculations are required to verify adequate water supply at the hydraulically most remote single sprinkler

when it is operating at the minimum gpm and psi listed for single-sprinkler operation for the sprinkler model used.

Viking residential sprinklers may be listed for more than one area of coverage. Suggested practice in selecting area of coverage is to select the one

that can be adequately supplied by the available water supply and still allow for the installation of as few sprinklers in a compartment as possible while

observing all guidelines pertaining to obstructions and spacing. This maximizes the use of the available water supply, which is often limited on residential

fire protection systems. After selecting an appropriate area of coverage, sprinklers must be spaced according to guidelines set forth in the installationstandards.

Definition of “COMPARTMENT”: A space completely enclosed by walls and a ceiling. Openings to an adjoining space are allowed, provided the open-

ings have a minimum lintel depth of 8 in. (203.2 mm) from the ceiling.

Spacing Guidelines

For guidelines concerning spacing of Viking residential sprinklers near beams, obstructions, heat sources, and sloped ceilings [slopes more than a

2/12 (9.5°) pitch], refer to the Viking residential sprinkler data pages and installation guide, the appropriate NFPA standard, and the Authority Having

Jurisdiction. NOTE: Sloped, beamed, and pitched ceilings could require special design features such as larger flow, or a design for more sprinklers to

operate in the compartment, or both.

Distance from Walls: Install not more than one-half the listed sprinkler spacing nor less than 4” (102 mm) from walls, partitions, or obstructions as

defined in the standards.

Minimum Sprinkler Spacing: The minimum distance between residential sprinklers to prevent cold soldering (i.e., the spray from one operating sprink-

ler onto an adjacent sprinkler that could prevent its proper activation) is 8 ft. (2.4 m).

Maximum Sprinkler Spacing: Locate adjacent sprinklers no farther apart than the listed spacing.

Deflector Position: Install frame style residential pendent sprinklers with the deflector between 1” and 4” (25.4 mm to 102 mm) below smooth ceilings,

unless the sprinkler data page indicates otherwise. Install pendent sprinklers in the pendent position only, with the deflector oriented parallel with the ceiling

or roof.

Refer to the individual listings in the residential sprinkler data pages for horizontal sidewall sprinkler deflector or sprinkler centerline distance below

the ceiling. Install horizontal sidewall sprinklers in the horizontal position only below smooth ceilings, with the leading edge of the deflector or element

assembly oriented parallel with the ceiling.

IMPORTANT: Always refer to Bulletin Form No. F_091699 - Care and Handling of Sprinklers. Also refer to the ap-

propriate sprinkler data page. Viking sprinklers are to be installed in accordance with the latest edition of Viking

technical data, the appropriate standards of NFPA and any other similar Authorities Having Jurisdiction, and also

with the provisions of governmental codes, ordinances, and standards, whenever applicable. Final approval and

acceptance of all residential sprinkler installations must be obtained from the Authorities Having Jurisdiction.

2. Apply a small amount of pipe-joint compound or tape to the external threads of the sprinkler only, taking care not to allow a

build-up of compound in the sprinkler inlet. NOTE: Sprinklers with protective caps or bulb shields must be contained within the

caps or shields before applying pipe-joint compound or tape. Exception: For concealed sprinklers (i.e., VK457, VK458, VK468

VK474, and VK4570) the protective cap is removed for installation.

3. Care must be taken when installing sprinklers on CPVC and copper piping systems. Never install the sprinkler into the re-

ducing fitting before attaching the reducing fitting to the piping. Sprinklers must be installed on CPVC systems after the

reducing fitting has been installed and the primer and/or cement manufacturer’s recommended curing time has elapsed

When installing sprinklers on copper piping systems, take care to brush the inside of the sprinkler supply piping and reducing

fitting to ensure that no flux accumulates in the sprinkler orifice. Excess flux can cause corrosion and may impair the ability of

the sprinkler to operate properly.

4. Refer to the appropriate sprinkler technical data page to determine the correct sprinkler wrench for the model of sprinkler used

DO NOT use the sprinkler deflector or fusible element to start or thread the sprinkler into a fitting.

a. Install the sprinkler onto the piping using the special sprinkler wrench only, while taking care not to over-tighten or damage

the sprinkler operating parts.

b. Thread the flush or concealed sprinkler into the ½” or 3/4” (15 mm or 20 mm) NPT** outlet of the coupling by turning it clock

wise with the special sprinkler wrench. NOTE: For flush and concealed sprinklers with protective shells, the internal diamete

of the special flush and concealed sprinkler installation wrench is designed for use with the sprinkler contained within the

shell. Exception: For concealed sprinklers VK457, VK458, VK468, VK474, and VK4570 the protective cap is removed for

installation, and then placed back on the sprinkler temporarily.

5. After installation, the entire sprinkler system must be tested. The test must be conducted to comply with the installation standards.

a. Make sure the sprinkler has been properly tightened. If a thread leak occurs, normally the unit must be removed, new

pipe-joint compound or tape applied, and then reinstalled. This is due to the fact that when the joint seal leaks, the sealing

compound is washed out of the joint.

b. Remove plastic protective sprinkler caps or bulb shields AFTER the wall or ceiling finish work is completed where

the sprinkler is installed and there no longer is a potential for mechanical damage to the sprinkler operating ele-

ments. To remove the bulb shields, simply pull the ends of the shields apart where they are snapped together. To remove caps

from frame style sprinklers, turn the caps slightly and pull them off the sprinklers. SPRINKLER CAPS OR BULB SHIELDS

MUST BE REMOVED FROM SPRINKLERS BEFORE PLACING THE SYSTEM IN SERVICE! Retain a protective cap o

shield in the spare sprinkler cabinet.

6. For residential flush sprinklers, the ceiling ring can now be installed onto the sprinkler body. Align the ceiling ring with the sprin-

kler body and thread on or push it on until the flange touches the ceiling. Note the maximum vertical adjustment is ½” (12,7

mm) for sprinkler VK420 and 5/8” for VK476. DO NOT MODIFY THE UNIT. If necessary, re-cut the sprinkler drop nipples as

required.

7. For residential concealed sprinklers, the cover plate assembly can now be attached.

a. Remove the cover plate assembly from the protective box, taking care not to damage the assembly.

b. From below the ceiling, gently place the base of the cover plate assembly over the sprinkler protruding through the opening

in the ceiling or wall.

c. Carefully push the cover plate assembly onto the sprinkler, using even pressure with the palm of the hand, until the unfinished

brass flange of the cover plate base touches the ceiling or wall.

d. The maximum adjustment available for residential concealed sprinklers is ½” (12.7 mm) [1/4” (6.4 mm) for sprinkler VK480][1/4” (6.4 mm) for sprinkler VK480]

DO NOT MODIFY THE UNIT. If necessary, re-cut the sprinkler nipples.

NOTE: If it is necessary to remove the entire sprinkler unit, the system must be taken out of service. See Maintenance instructions

below and follow all warnings and instructions.

5. OPERATIONDuring fire conditions, the operating element fuses or shatters (depending on the type of sprinkler), releasing the pip cap and seal-

ing assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector or flow shaper, forming a uniform, high-wal

wetting spray pattern to extinguish or control the fire.

6. INSPECTIONS, TESTS AND MAINTENANCEINSPECTIONS, TESTS AND MAINTENANCERefer to NFPA 25 for Inspection, Testing and Maintenance requirements. NOTICE: The owner is responsible for having the fire-

protection system and devices inspected, tested, and maintained in proper operating condition in accordance with this guide, and

applicable NFPA standards. In addition, the Authority Having Jurisdiction may have additional maintenance, testing, and inspection

requirements that must be followed.

A. Sprinklers must be inspected on a regular basis for signs of corrosion, mechanical damage, obstructions, paint, etc. Frequency

of the inspections may vary due to corrosive atmospheres, water supplies, and activity around the device.

B. Sprinklers or cover plate assemblies that have been field painted, caulked, or mechanically damaged must be replaced im-

mediately. Sprinklers showing signs of corrosion shall be tested and/or replaced immediately as required. Installation standards

require sprinklers to be tested and, if necessary, replaced immediately after a specified term of service. Refer to NFPA 25 and

the Authorities Having Jurisdiction for the specified period of time after which testing and/or replacement of residential sprinklers

is required. Never attempt to repair or reassemble a sprinkler. Sprinklers and cover assemblies that have operated cannot be

reassembled or re-used, but must be replaced. When replacement is necessary, use only new sprinklers and cover assemblies

with identical performance characteristics.C. The sprinkler discharge pattern is critical for proper fire protection. Nothing should be hung from, attached to, or otherwise ob-

struct the discharge pattern of the sprinkler. All obstructions must be immediately removed or, if necessary, additional sprinklers

installed.

D. When replacing existing sprinklers, the system must be removed from service. Refer to the appropriate system description and

or valve instructions. Prior to removing the system from service, notify all Authorities Having Jurisdiction. Consideration should

be given to employment of a fire patrol in the effected area.

1. Remove the system from service, drain all water, and relieve all pressure on the piping.

2a. For frame-style sprinklers, use the special sprinkler wrench and remove the old sprinkler by turning it counterclockwise to

unthread it from the piping.

2b. For residential flush pendent and concealed style sprinklers: Remove the ceiling ring or cover plate assembly before unthreading the

sprinkler body from the piping. To remove a ceiling ring, grasp it from below the ceiling and gently turn it counterclockwise. Cove

plates can be removed either by gently unthreading them or pulling them off the sprinkler body (depends on the sprinkler model used)

After the ceiling ring or cover plate assembly has been removed from the sprinkler, use the sprinkler wrench to unthread

the sprinkler from the piping. NOTE: For flush and concealed sprinklers with protective shells, the internal diameter of thespecial flush and concealed sprinkler installation wrench is designed for use with the sprinkler contained within the shell

Place a plastic protective shell (from the spare sprinkler cabinet) over the sprinkler to be removed and then fit the sprinkle

wrench over the shell. Exception: Concealed sprinklers VK457, VK458, VK468, VK474, and VK4570 are removed withou

the plastic cap.

3. Follow instructions in section 4B. Installation Instructions to install the new unit. Be sure the replacement sprinkler is the

correct model and style, with the appropriate K-Factor, temperature rating, and response characteristics. A fully stocked

sprinkler cabinet should be provided for this purpose. (For flush or concealed style sprinklers, stock of spare ceiling rings o

cover plates should also be available in the spare sprinkler cabinet.)

4. Place the system back in service and secure all valves. Check for and repair all leaks.

E. Sprinkler systems that have been subjected to a fire must be returned to service as soon as possible. The entire system mus

be inspected for damage, and repaired or replaced as necessary. Sprinklers that have been exposed to corrosive products of

combustion or high ambient temperatures, but have not operated, should be replaced. Refer to the Authority Having Jurisdiction

for minimum replacement requirements.

Where residential sprinklers will be exposed to the rays of the sun passing through glass or plastic skylights, use inter-

mediate temperature rated sprinklers.

When locating residential sprinklers in an unventilated concealed compartment, under an unventilated attic or unin-

sulated roof, where the maximum ambient temperature does not exceed 150 °F, use intermediate temperature rated

sprinklers.

Ordinary temperature rated residential sprinklers (135 °F to 170 °F rated) are only to be installed where the maximum ambient

ceiling temperature will not exceed 100 °F. Where the maximum ambient ceiling temperature will be from 101 °F to 150 °F, use

intermediate temperature rated residential sprinklers (175 °F to 225 °F rated).

Residential sprinklers must be positioned a sufficient distance away from heat sources that include fireplaces, stoves, kitchen

ranges, wall ovens, hot water pipes, water heaters, furnaces and associated flues and ducts, and light fixtures. The following

minimum distances must be maintained for both ordinary and intermediate temperature rated residential sprinklers as indicated.
